What are sulci and fissures?
Brain fissures, also known as sulci, are the prominent grooves that traverse the surface of the cerebral cortex, dividing it into distinct gyri or ridges. These intricate folds are a hallmark feature of the human brain, contributing to its remarkable complexity and functional specialization.
Aug 19, 2021 · Cerebral sulci and fissures are grooves between the adjacent gyri on the surface of the cerebral hemispheres. By allowing the cortex to invaginate to form sulci and gyri the surface area of the cortex is increased threefold 4.

A fissure or sulcus is a natural division, deep furrow, or a groove that separates the gyri of the brain. The main groove of the brain is the interhemispheric fissure which divides the brain into two halves. Interhemispheric Fissure. When the external surface is explored from above a fissure divides the oval of the brain into two hemisphere.
Aug 10, 2023 · In this way, fissures of the skull are very similar to foramina, in that they are also passageways through bone. They are called fissures simply because they are a different shape of hole, they look more like a crack or cleft, and typically occur between separate anatomical structures.

The longitudinal fissure (or cerebral fissure, great longitudinal fissure, median longitudinal fissure, interhemispheric fissure) is the deep groove that separates the two cerebral hemispheres of the vertebrate brain.
Aug 28, 2023 · The Sylvian fissure is the most consistent and distinct landmark of the lateral hemispheric surface of the brain. It is formed by the anatomical relationship between the frontoparietal operculum, the temporal operculum, and the insula.
